Inculpas comes from the verb inculpar, meaning "to accuse" or "to incriminate". It's a more formal and less common word than acusar (to accuse), making it stand out in the lyrics.
In the song, the artist sings, "Soy inocente de lo que me inculpas" (I am innocent of what you accuse me of). This line highlights a moment of defensiveness and misunderstanding in the relationship, adding a layer of drama and intrigue to the narrative.
Marc Seguí and Micro TDH's "La Culpa" is a super relatable song about a guy who messed up a good thing and is now drowning in regret. He admits, "Fui un idiota, yo te descuidé, lo admito" [I was an idiot, I neglected you, I admit it], taking responsibility for losing the person he loved. He's clearly struggling, drinking alone, and missing everything about her, from her skin to her kisses. He even says, "Si no me besas, no sigo respirando" [If you don't kiss me, I don't keep breathing], which is pretty intense!
What's really interesting is how he tries to shift blame a little, asking "Y quién tuvo la culpa" [And who was to blame?] and then immediately saying, "Soy inocente de lo que me inculpas" [I'm innocent of what you accuse me of]. It's like he's trying to justify himself even while he's begging for another chance, promising, "Vamos a intentarlo una vez más, que esta va a ser la buena" [Let's try one more time, this one's going to be the good one]. He's clearly heartbroken seeing her happy with someone else, and you can feel his desperation to win her back. It's a raw look at post-breakup regret and the messy feelings that come with it.
